Have a check the headboards, bed frames, mattresses, door and window frames, light fixtures, wall hangings, tables, chairs, sofas, and curtains.
Bed bugs leave highly visible, itchy, red bite marks on the skin, often on the neck and arms.
Another identifying feature is their excrement, which can be found as small dark spots on sheets, mattresses, bed frames, pillows, blankets, and other places where people spend time. They may also leave small bloodstains on these same places.
Finding dead individuals is another certain indicator of the existence of a plague. Once bed bugs have accessed the building structures, only pest control experts can eradicate them.
